Yep I do it every chance I get. I uninate in every scrape I can. It works too, I have the photos to prove it.

Heck I' ve got a good one for you. A couple weeks ago I found a small dried up scrape on an old grown over log road. I cleaned the leaves out with a stick and urinated in it. 2 days later I came back and there were 4, count them 4 NEW scrapes, on the log road within 20 yrds of the one I urinated in. The original scrape I urinated in had been cleaned out and was alot bigger than before. There was also a new scrape within 3 ft of it, under another limb on the same tree.
